LIGHT-REFLECTIN G DEVICE.

Specification of Letters Patent.

Application filed May 9, 1913. Serial No. 766,482.

ficationl.

My: inventionrelates to improvements in illuminating devices or light reflecting fixtures: embodying a. new and useful construction in a chandelier or portablelightingdevice adapted toreflect the rays of light from the burner upwardly againstthe ceiling, and also to diffuse the downwardly and outwardly projected rays for the purpose of illuminatin a shade or bowl adapted to conceal the main reflector and the source of light, and also to produce an ornamental efi'ect desirable in articles of this class.

The especial object of this invention is to provide an. opaque reflector, and a glass light diflusing member in combination therewith, for the purpose above stated that will embody certain features not covered by my co-pending application under Serial No! $15,096, which issued as Patent No.

1,084,809,,Jan. 20, 1914.

In the accompanying drawings forming a part of this application, I have illustrated a preferred embodiment of my invention, in which a Figure l is a view, partly in section and partly in elevation, of my improvement,

showing it embodied in a portable or standlamp; Fig. 2 is a view partly in section and partly in elevation of my improvement showing it embodied in a suspended chandelier fixture. y

Referrin to the details of Fig. 1 of the drawing, t e reference character 3 designates a lamp standard of any suitable design or size, and adapted to support at its up erend an electric lamp holder or socket 4, aving radially extending arms 5, supporting at their outer ends incandescent lamps 5} one of which is shown in Fig. 1. Supported-oaths socket 4:, and extending upwardly therefrom, is a lamp socket 4, oi commonform, incased in a metal collar 8, on the upper portion of which is suitably mounted a flanged ring 7. Supported on the socket 4 at a point above the on shaped ring 7, is a metal ring 8 from whic extend upwardly and outwardly, curved qa-rt ofthe light from the electric lamp 9,

arranged within the reflector 11, will be thrown upwardly. The upper edge of said reflector 11 is flanged as at 11 to enter depressions 10 in the upper ends of the frame members 10. From 10 the members 10 are bent to form a flange 1O which is adapted to receivev and. support the upper edge of a shade 12, which may be partially transparent, or may be a reflector that will catch and direct downwardly the rays of light from the lamps 5. To provide for the diffusion of the rays of light that pass downwardly through the central opening 11?, in the, reflector 11, and also from that portion of the lamp 9 that extends below the bottom of the reflector, I arrange preferably an opal glass diffuser 12, bowlshape, the bottom edge 12 of which fits into, and is supported by, the cup shaped member 7. The walls of the diffuser 12 are comparatively thin at their extreme upper edge and then gradually increase in thickness up to the point where the rays of light from the lamp 9 are the strongest, thus uniformly or evenly diffusing the said rays. It is not my desire, however, to restrict myself to the use of the above described combination of reflector and difl'user in stand lamps, as the sameidea may be successfully embodied in a suspended chandelier as I have shown in Fig. 2.

A translucent bowl of glass 15, of any desired shape or ornamental finish. is formed with an outwardly flaring edge 15 to which is fitted a metal band 13, which is suspended from the ceiling (not shown) by means of chains 14 suitably secured to the band 13, preferably by hooks 13 as shown. Extending upwardly through the bottom of the bowl 15 is a threaded bolt 17, which passes through an ornamental sheet-metal member 16, the threads of said bolt engaging a nut 18 secured to the collar 6, heretofore described, thus forming a support for the Patented Dec. 15, 19121.

' combination, a lighting unit, a reflector, and

diffusing member constructed and arranged as described, will not only effectivelyilluminate the ceiling, thus indirectly lighting the room, but will also diffuse a portion of the outwardly and downwardly projecting light flux or rays, thus illuminating a bowl or shade, either of which may be adapted to conceal the reflector diffuser and light-ingunit, thus producing an ornamental effect and also illuminating objects arranged to fall within the zone of the downward rays.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. An illuminating device comprising suitable means for supporting in an upright position an incandescent lamp socket, a frame supported by'said socket, an opaque reflector supported by said frame having an opening in its bottom and adapted to reflect a portion of the rays of light from a lamp in said socket'in an upwardly and outwardly direction, a bowl-shaped member arranged below said reflector and surrounding the opening in the bottom thereof, and adapted to diffuse the light rays extending downwardly from said lamp.

2. An illuminating device comprising an incandescent lamp socket, a reflector supported from said socket and adapted to reflect a portion of rays'of light from a lamp in said socket in an upwardly and outwardly direction, a bowl-shaped member supported by said socket, adapted to surround the lower portion of said lamp, and to diffuse light rays extending downwardly and outwardly from said lamp, and a plurality of lamps extending radially from the lower portion of said socket, and below said diffuser member.

3. In an illuminating device, a lighting unit, an opaque reflector surrounding said lighting unit and open at its bottom, a lightdiflusing member arranged below and surrounding the lower portion of said light.-

ing unit below said reflector, the walls of said diffusing member varying in thickness.

4. In an illuminating device, a lighting unit, an opaque reflector surrounding said lighting unit and open at its bottom, a light diffusing member arranged below a lighting unit, the walls of said diffusing member extending upwardly and outwardly, surrounding the lower portion of the lighting unit and 1 the opening in said reflector, the walls of said diffusing member gradually increasing in thickness from their upper edge downwardly.

In testimony whereof I afiix my signature in the presence of two witnesses.
